Molybdenum Crucible
Product Molybdenum Crucible (Mo Crucible)
Part Number TRM-MO014
Purity 99.95%
Type Seamless or Welded
Density 10.2 g/cm3
CAS# 7439-98-7

Molybdenum crucible is usually made from the pure molybdenum powder with purity up to 99.95%. The density of molybdenum crucible is more than 9.8 g/cm3, and its working temperature ranges from 1100℃ to 1700℃ in the vacuum environment.

The lid is not always necessary, but the molybdenum crucible can be manufactured with a lid to be a set. The lids can have different shapes, like a round one with a hole in the middle. For the application of melting metal, it should be sloping placing for oxygen exchanging to prevent fluid inside from spraying. Please refer to the Mo Sheet for other Molybdenum products.

Application: Molybdenum crucible is widely used in the core container of the sapphire single crystal growth furnace, the quartz glass melting furnace, the rare earth smelting furnaces, the metallurgical industry and etc.

Thermostability 89%
Machinability 85%
Corrosion Resistance 88%

Sintered Molybdenum Crucible

It undergoes the pressing, sintering and machining. And it can be offered in large sizes. The density is 9.5-9.8 g/cm3.

The outer diameter ranges from 0.4’’ to 20’’ and the height ranges from 0.4’’ to 23.5’’.

Forging Molybdenum Crucible

It undergoes the pressing, sintering, forging and machining. The molybdenum crucible is produced by a forging press to achieve the size, mechanical properties, and shapes. The density is 10.1 g/cm3 min.

The outer diameter ranges from 0.4’’ to 5’’ and the height ranges from 0.4’’ to 7.8’’.

Welded Molybdenum Crucible

It is produced by welding process, which can lower the cost. However, since the weldability of the molybdenum is not good, the wall thickness can not be very thick and the air tightness is not high.

It’s now widely used in Bridgman-Stockbarge method single crystal growth furnace. We can supply 2’’,4’’ and 6’’ Welded Molybdenum Crucibles.
